There are several ways to get ahold of clammbon releases outside of Japan. I personally use YesAsia, because their prices are right, they have good service, and they often offer free shipping. You can also try Play-Asia or CDJapan. If you use one of the following links, any purchase you make will help support this site; I promise to use that money to buy more clammbon products to document on this site! Thanks!

Perpetual thanks to the official clammbon site. Few bands are so kind to their fans.
